Dear
Welcome to HCM
I understand your concern.
May be you are at your maximum height of
stress.
You are 60 and you witnessed a death of brother and mother is terminally ill also.
Most probably you are realizing that your fate would also be something like that.
But is it true?
This is the time you should have full faith in god.
He created you, nurtured you,developed you etc. and when he wishes, he will take you with him.
That is the truth.
Truth is always bitter, and now your trying to deny the truth, worry about future, health etc.
Forget all. You are now good.But nobody can say what is tomorrow.
Why worry about what you are not certain or about what you cannot control?
Be happy now. Thats all.
Bible says: Live life as if today is your last day in life, and enjoy.
